As if raking in more than $200 million on its opening weekend wasn’t already a heroic accomplishment, “Black Panther” has also won the heart of Michelle Obama.

The former first lady made a rare appearance Monday on Twitter to offer words of praise to the cast and crew of the movie. “Because of you, young people will finally see superheroes that look like them on the big screen,” she wrote. “I loved this movie and I know it will inspire people of all backgrounds to dig deep and find the courage to be heroes of their own stories.” Obama has posted fewer than 20 tweets since Jan. 1, usually commenting on political issues or sending a loving message to husband Barack Obama.

Director Ryan Coogler’s blockbuster starring Chadwick Boseman shattered box-office records on its opening weekend. It is expected to take in an estimated $235 million domestically for the four-day holiday weekend, making it the highest-grossing motion picture made by an African-American filmmaker.
